Description
The AT25F1024A provides 1,048,576 bits of serial reprogrammable Flash memory
organized as 131,072 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operation
are essential. The AT25F1024A is available in a space-saving 8-lead JEDEC SOIC
and 8-lead SAP packages.
The AT25F1024A is enabled through the Chip Select pin (CS) and accessed via a 3-
wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial
Clock (SCK). All write cycles are completely self-timed.
BLOCK WRITE protection for top 1/4, top 1/2 or the entire memory array is enabled by
programming the status register. Separate write enable and write disable instructions
are provided for additional data protection. Hardware data protection is provided via
the WP pin to protect against inadvertent write attempts to the status register. The
HOLD pin may be used to suspend any serial communication without resetting the
serial sequence.
